Government forms + official documents

Hi,
As I've been working with legal aid groups + advocacy orgs to mark up their site, I'm wondering how best to mark up the official government forms and other legal documents that are on their site.

These forms are like a
- an official CDC declaration form to fill out and give to your landlord to protect yourself from eviction
- a court document to file or answer a lawsuit
- a USCIS form to fill out to apply for a visa

Has anyone used any mark up strategy to designate an official government document or a legal aid-generated template/form for people to use in a legal setting? This might also be a term that would be a valuable addition under CreativeWork.

Thanks! Best, Margaret
